+DAS Settings
+Jalview can retrieve sequences and features from many DAS sources. The DAS sources that +it uses are discovered and selected via the DAS settings panel, +opened either from the View→Feature +Settings dialog box from the alignment window's menu bar, or the Tools→Preferences dialog box +opened from the Desktop menu bar.
+
+
The available sources are listed in the table using each source's +Nickname as its identifier. Clicking on a source's entry in the table +reveals more information about that service in the panel to the right. +Select the tickbox in the "Use Source" column for a source to +add it to the set Jalview queries for alignment and sequence features.
+You can filter the visible DAS sources by authority, type and +"label". You should read the DAS documentation to understand +more about these values. +
Updating the list of sources
+When the DAS Settings panel is first opened, and when the 'Refresh +source' buton is pressed, a list of DAS sources is retrieved from the +DAS registry URL (set by default to the DAS registration server at +http://das.sanger.ac.uk/registry/das1/sources/).
+Adding your own DAS Sources
+You can add your own DAS source to the list by clicking the +"Add Local Source" button. Enter the URL and nickname of your +additional service. It should be noted that Jalview 2.1 will not query +additional sources for more information, but this will be implemented in +future editions. +
